Question

express the double integral over the indicated region R as an iterated integral, and find it's value
doubleint of region R of xy^2
region = triangle with vertices (0,0) (3,1), (-2,1)

Answer 1

I'm sorry I actually have to go now, but what you want to do is find the equation of the lines between the vertices. From there you can develop some bounds of integration. Then you would integrate\[xy^2 \;\;\;\;dx\;dy\]or\[xy^2\;\;\;\;dy\;dx\]Depending on your preference.
